Revealing the dangers of "arsenic" after it was found contaminating the Kok River. Learn to recognize symptoms of acute and chronic poisoning, along with ways to protect yourself when using water containing this contaminant.
The recent detection of "arsenic" contamination in the Kok River has caused significant concern among local residents, as the river is a major source of water for consumption and use. Thairath Online explores what arsenic is, where it can be found, and how exposure affects health, so you can be properly prepared to protect yourself.
Arsenic is a naturally occurring element found in soil, rocks, and water. It can also result from human activities such as mining, pesticide use, or industrial processes. Generally, arsenic in the environment exists in two forms: organic and inorganic arsenic, with the latter being much more toxic.
The frightening aspect of arsenic is that it cannot be detected by sight or smell when dissolved in water. Once it enters the body, it causes the following effects:
If a large amount of arsenic is ingested at once, symptoms include severe nausea, vomiting, abdominal pain, bloody diarrhea, low blood pressure, which can lead to shock or death.
Long-term, low-level exposure to arsenic, such as drinking contaminated water, affects various body systems as follows:
Because arsenic is colorless, odorless, and tasteless, it is very difficult to detect visually in water. However, "warning signs" can be observed from environmental factors and bodily symptoms as follows:
If groundwater or natural water sources contain abundant reddish-brown sediment (iron rust), it may indicate high heavy metal contamination in the soil, often including arsenic.
If crops in the watershed area show signs of leaf burn, stunted growth, or unusual yield reduction, it may be due to arsenic absorption from soil and water into their roots. Additionally, aquatic animals like fish and frogs may show red-purple tumor-like nodules on fins, tails, whiskers, and around the mouth. Some may have sores, infections, ulcers, or external parasites. Affected fish usually appear lethargic and weak due to secondary infections.
For residents living in high-risk areas or using water from the Kok River basin, the following measures are recommended:
The discovery of arsenic in the Kok River is a matter requiring close monitoring. Residents should follow announcements from public health agencies and the Pollution Control Department regularly to assess water safety. If arsenic poisoning symptoms are suspected, immediate medical check-ups are advised.
